IMPROVEMENT IN HANDSPINNING MACHINES.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, NATHAN M. MENDENIIALL and JAMES JUDD, of Terre Haute, Vigo county, and State of' Indiana, haveinvented a new andimproved Spinningr Machine, of which the following is aiull and clear description, reference being had to the accompanying drawings, making a part of this specification.

Figure l is a perspective view of our improved spinning machine.

Figure 2 is a longitudinal sectional elevation oi' the front end of' the machine.

Figure 3 is a detached view, showing an adjustable device for feeding the material from an endless apron Aon the reciprocating carriage which traverses upon the side rails ofthe frame of' the machine.

Figure 4 is a detached view embracing the device for changing the motion of the reciprocating carriage.

A. is the frame of the machine, to the front end rails a a of which is journalled Vthe series of spindles B inclining inward at top. They are provided with pulleys Zz, which carry the driving-belts c. The belts c pass about drum d journallcd upon the lower side rails c of the frame A at a convenient distance from the front end of the machine. The axle ot' drum d is continued outside of the frame A, and hears the pulley f, about which passes the main driving-belt g; it is continued around the crank-wheel L. The axle i of crank-wheel ii is journalled to the front corner-post ic and auxiliary post k', without yet making part of frame A. A large gearwheel Z is secured to the axle i; it meshes into a corresponding gear Z upon the axle l, directly beneath axle 1'., Each axle Z and z' is provided with pinions m kand n. Between them is the reversing pinion o journalled to the lever p. The lever p is pivoted at its elbowp. The long arm p terminates in the handlepm. A bar, q, having upon one edge the notches 1, 2, 3, for the purpose of receiving the long arm p" of the lever 1J, projects to the front from frame A. The spring 4, secured at either end to the bar g, confines the long arm pin one of the notches 1, 2, or 3. The axle 1', which bears the reversing pinion o, carries on its extreme end, within the frame A, the pulley s. A belt, s', passing about it, extending to the rear ofthe machine, is carried over the small roller s, and is made fast to the under side of carriage C.` The power member of belt s passes beneath the carriage C, to which it is also made fast. Two standards t, erected from the side rails of the carriage C, carry the reel u, having the crank-handle u on the right. The front roller 2r, which carries the endless apron n", has its axle continued at either end without the side rails of the carriage C. The left-hand end has secured it the ratchet=l wheel o", which is engaged by the pawl om pivoted to the frame of the carriage C. The projecting right-hand end of the axle of the front rollerv has secured to it the ratchet-wheel w, outside of'which, upon the same axle, is the loose gearewheel w. It has the ratchet zu pivoted to its inner face, and engaging the ratchet-wheel w. The rgear-wheel w meshes into the pinion w", which is the medium for giving motion to the apron when the carriage C moves backward. The pinion w engages for a limited distance the rack-bar 9:, attached to the side rail of the frame A. The bar x is adjustable, the bolts a passing through the slots as in the rackbar x. Between the front corner posts of the frame A, and at the same height as the side rails upon which the carriage C traverses, is located the freely revolving roller y, to which is secured the vibrating-bar y. From a staple in face of the roller a cord, y, is carried about the roller y" near the foot of trip-bar ym', thence over the rolleryf" placed on the inside of the right-hand side rail, and is nally secured to the earn-bar 5. Said cam-bar is pivoted at its foot to the lower front rail of the frame A, and it is caused to bear constantly upon the cam (i, secured to the axle r by the tension of the cord y, the spring 7, attached to a staple in the roller y, and to the corner post of the frame A, producing Athe desired tension, and elevating the vibrating bar y over the tops of the spindles B, when the amplitude of the cams motion is least.v -The trip-bar 31, to which the. roller y'" is pivoted, is passed between the long loop 8, secured longitudinally to the inner face of the upper side rail of the frame A. The rear edge of the trip-bar is notched to engage the loop 8. The upper end of the trip-bar is rounded oii` on the inner side at a level with the roller 'v of the carriage C. A link, 9, connects the centre of trip-bar with the inner end of the hand-lever 10, which is pivoted immediately above-the lower front rail of thc`i`rarne A, the handle extend ing outwards. An adjustable roller v is located immediately over front roller t'.

Operation. The woollen or othermaterial to be spun, is, after being carded, placed upon the endless apron n, the car ringe C is drawn to the front of the machine close to the spindles B, the rolls are passed beneath the adjustable roller if', und their ends secured to the spindles B, the vibratngibary being elevated above the ends of the spindles, as shown in g. 1. Previous to operating, the arm p of the levcrp is sprung into outside notch 3 in the bar g, as shown in the accompanying drawing. The operator, with the handle-21 of the leverp in the left hand, gives a forward motion to the crank-wheel L with the right hand, thereby imparting mot-ionto all the working parts of the machine, and causing the carriage C to move gradually to the rear, feeding ont the rolls from the apron c only during the first period of backward motion, when the pinion wl, which is pivoted to the carriage C, meshes into the rack-bar x, which permits the formation of a thread of sntheient strength near the spindles B to prevent the rolls parting from them during the balance of the backward movement ofthe carriage C. In the mean time the spindles have suicient motion imparted to them from the drum d to partly twist the attenuated rolls. The carriage C having reached the limit of backward motion remains at rest while the yarn is being spun. In order to more easily increase the speed of the spindles and relieve the balance of the maohineryythe arm p ofthe leverp is sprung into notch 2 of the bar q'. The handle p" is moved back until the arzn p is engaged by the notch 1, the forward motion being still imparted to the crank-wheel z, thus reversing the motion of the carriage C and bringing it to the front. As the carriage approaches the front, the

veam 6 presses out the cam-bar 5, and by means of cord y presses down the vibrating bar y. The thread is wound upon the spindles from top to bottom. 'At the same time that the pinion 10"" engages the, rack-bar x, thus causing the apron to feed out the rolls, the free end of the trip-bary" is pressed by the front end of the advancing lcarriage C, which frees the notched edge of the bar g/H from the long loop 8, and relie-ves the tension in cord y. The spring 7 is enabled to rotate the roller 1, throwing up the vibrating-bar y. The spindles still continuing to rotate, Ithe thread, during the remaining time, since the carriage C struck the trip-barg/H until ithas reached the extreme front, is wound from the bottom to the top. To pnt the thread or yarn thus spun into a portable shape, the ends ofthe threads. on the spindles are attached to the reel u without passing beneath the roller v. The operator, by means of crank-handle u', rotates the reel until the hanlis are formed. If heavy yarn or thread is required, the ends of threads from two or more hanks, while still upon the neel, are carried beneath the rolle!` v and secured to the spindle B. The twisting is then proceeded with, as in the operation above described for producing the first thread from the roll.

Having described our improved spinning machine, we claim as our invention, and desire to secure by Letters Patent- 1. The lever p, notched bar g, reversing pinion o, gear-wheels l and l', and pinions m and a, pulley s and cord s', in combination with the carriage C, `as and forvthe purpose specified and set forth. l

2. The vibrating bar y', spring 7, cord y, trip-bar ym', link 9, lever 10, cam-bar 5, and cam 6, arranged and operating substantially as above described and for the purpose specified.
